Abstract

Sistemas y métodos para la formación de haces adaptable para un sistema móvil por satélite (MSS); las modalidades que se describen en la presente memoria proporcionan una formación de haces adaptable y optimizada por el usuario individual; un sistema de ejemplo crea un haz de usuario optimizado según las ubicaciones de usuario conocidas o las formas de onda recibidas de todos los usuarios del cocanal; el haz de usuario maximiza la señal/ruido e interferencia con respecto al usuario deseado, tanto en los enlaces directos como en los de retorno; el proceso de optimización considera la distribución espacial de todos los usuarios del cocanal en la huella del satélite; el haz de usuario se adapta a la ubicación del usuario y el entorno de interferencia del cocanal.
